Sentences with phrase «polar sea ice continues»

Not exact matches

The case of this one polar bear and the failure of her offspring to survive in the new environmental conditions of the Arctic doesn't bode well for the future of the species, especially as Arctic sea ice continues to retreat at a record pace.

The U.S. Department of the Interior Wednesday listed the polar bear as a threatened species under the Endangered Species Act (ESA) of 1973 based on evidence that the animal's sea ice habitat is shrinking and is likely to continue to do so over the next several decades.

The decision was based on evidence that sea ice is vital for polar bear survival, that this sea ice habitat has been reduced, and that this process is likely to continue; if something is not done to change this situation, the polar bear will be extinct within 45 years, Kempthorne said.

The continuing warming and summertime retreats of sea ice around the North Pole are making life difficult for seal - hunting polar bears, eroding Inuit coastal villages and now, evidently, eroding Arctic defenses (although not weakening them, the Pentagon insists).

Excerpt: Livermore CA (SPX) Nov 01, 2005 If humans continue to use fossil fuels in a business as usual manner for the next several centuries, the polar ice caps will be depleted, ocean sea levels will rise by seven meters and median air temperatures will soar 14.5 degrees warmer than current day.

Ms. Gormezano is not a fan of the forecasting methods used by Dr. Amstrup to conclude that a two - thirds reduction in polar bears is possible midcentury if summer sea ice continues retreating.

If both Greenland and West Antarctica shed the entirety of their ice burden, global sea levels would rise by 12 to 14 m. Although these icecaps would not disintegrate within a century, the loss of even a third of their mass — quite plausible if the rate of polar ice loss continues to double each decade — would force up the oceans by at least 4 m, with disastrous socioeconomic and environmental consequences.

Despite Center for Biological Diversity assertions that «Arctic sea ice melt is a disaster for the polar bears», research shows polar bear populations have continued to thrive and increase.

... observations suggested the bears drowned in rough seas and high winds and «suggest that drowning - related deaths of polar bears may increase in the future if the observed trend of regression of pack ice and / or longer open water periods continues.»

Recent trends in the decline of Arctic polar sea ice extent continued in 2016.

For example, reductions in seasonal sea ice cover and higher surface temperatures may open up new habitat in polar regions for some important fish species, such as cod, herring, and pollock.128 However, continued presence of cold bottom - water temperatures on the Alaskan continental shelf could limit northward migration into the northern Bering Sea and Chukchi Sea off northwestern Alaska.129, 130 In addition, warming may cause reductions in the abundance of some species, such as pollock, in their current ranges in the Bering Sea131and reduce the health of juvenile sockeye salmon, potentially resulting in decreased overwinter survival.132 If ocean warming continues, it is unlikely that current fishing pressure on pollock can be sustained.133 Higher temperatures are also likely to increase the frequency of early Chinook salmon migrations, making management of the fishery by multiple user groups more challenging.sea ice cover and higher surface temperatures may open up new habitat in polar regions for some important fish species, such as cod, herring, and pollock.128 However, continued presence of cold bottom - water temperatures on the Alaskan continental shelf could limit northward migration into the northern Bering Sea and Chukchi Sea off northwestern Alaska.129, 130 In addition, warming may cause reductions in the abundance of some species, such as pollock, in their current ranges in the Bering Sea131and reduce the health of juvenile sockeye salmon, potentially resulting in decreased overwinter survival.132 If ocean warming continues, it is unlikely that current fishing pressure on pollock can be sustained.133 Higher temperatures are also likely to increase the frequency of early Chinook salmon migrations, making management of the fishery by multiple user groups more challenging.Sea and Chukchi Sea off northwestern Alaska.129, 130 In addition, warming may cause reductions in the abundance of some species, such as pollock, in their current ranges in the Bering Sea131and reduce the health of juvenile sockeye salmon, potentially resulting in decreased overwinter survival.132 If ocean warming continues, it is unlikely that current fishing pressure on pollock can be sustained.133 Higher temperatures are also likely to increase the frequency of early Chinook salmon migrations, making management of the fishery by multiple user groups more challenging.Sea off northwestern Alaska.129, 130 In addition, warming may cause reductions in the abundance of some species, such as pollock, in their current ranges in the Bering Sea131and reduce the health of juvenile sockeye salmon, potentially resulting in decreased overwinter survival.132 If ocean warming continues, it is unlikely that current fishing pressure on pollock can be sustained.133 Higher temperatures are also likely to increase the frequency of early Chinook salmon migrations, making management of the fishery by multiple user groups more challenging.Sea131and reduce the health of juvenile sockeye salmon, potentially resulting in decreased overwinter survival.132 If ocean warming continues, it is unlikely that current fishing pressure on pollock can be sustained.133 Higher temperatures are also likely to increase the frequency of early Chinook salmon migrations, making management of the fishery by multiple user groups more challenging.134

Instead of fixing the black carbon (soot) pollution they are responsible for, the EU activists continue to rail about the atmospheric trace gas CO2, which, by the way, doesn't melt glaciers, sea ice or polar ice sheet caps.

While the dramatic loss of weight has not led to a decline in the population of polar bears, that could change as a warming Arctic continues to melt away sea ice.

The U.S. Department of the Interior announced on December 27 that it is proposing formally to list the polar bear as «threatened» with extinction, because rising Arctic temperature is causing the loss of sea ice, on which polar bears depend... Continue reading →

In a February report, Dr. Parkinson said, «If trends toward shortened sea ice seasons and lesser sea ice coverage continue, this could entail major consequences to the polar and perhaps global climate, and to the lifestyles and survivability of selected Arctic plant and animal species.»

«Two findings were most critical to FWS's listing determination: (1) extensive declines in Arctic sea ice extent already have occurred and are projected to continue; and (2) the polar bear depends on sea ice for its continued survival as a species.

And since we have had rising sea level over last couple centuries, and this generally indicates warming global ocean volume, I expect this trend to continue for the next century [most likely] and due to warming oceans continuation of tread of less polar sea ice.

Marine mammals living in the polar regions rely on sea ice, and continuing reductions in the amount of ice will harm populations of seals, walruses, and polar bears.
